A tiered approach

Tier 1 - Full Support

Tier 2 - User can perform basic tasks and good support of design and layout, but some allowance for design elements that degrade or do not render exactly as designed (e.g., a button appearing with angled rather than rounded corners).

Tier 3 - User can perform basic tasks and all pages are readable and navigable, but the aesthetic quality of the site may be lowered significantly (e.g., system buttons rather than designed buttons).
